While psychedelic rock began to waver at the end of the 1960s, psychedelic soul continued into the 1970s, peaking in popularity in the early years of the decade, and only disappearing in the late 1970s as tastes began to change.[2] Acts like Earth, Wind and Fire, Kool and the Gang and Ohio Players, who began as psychedelic soul artists, incorporated its sounds into funk music and eventually the disco which partly replaced it.[7]
